앞에서 임프란트 주변 연조직의 형태를 작업모형에서 재현하기 위한 몇가지 방법을 살펴 보았다. 심미성이 점차 강조되고 있는 추세에 비추어 단순하게 치아의 심미성 보다는 전반적으로 연조직과 경조직이 잘 조화되는 수복물이 요구되고 있다. 잘 만들어진 작업모형은 좀 더 심미적이고 안정된 결과를 얻을 수 있도록 도움이 될 것이다.

With the increasing demand for aesthetic implant dentistry, the importance of implant restoration is emphasized not only in the functional aspect but also in the aesthetic aspect. The aesthetic restoration of dental implants in the anterior maxilla is a challenge for clinicians because it requires proper harmony in three following conditions; reconstruction of hard tissue, soft tissue, and aesthetic prosthesis. The soft tissue aesthetics are dependent upon the condition of the supporting hard tissue because the osseous structure provides a framework for the development of a healthy and aesthetic soft tissue interface. Therefore, the augmentation of hard tissue is a first step and especially, optimal 3-dimensional position of implant is the most important factor in aesthetic implant restoration. The management of soft tissue is a second step, and the final step is a restoration of harmonic prosthesis using provisional restoration with proper emergence profile. This clinical report describes the procedure of bone augmentation in labial dehiscence defect, Vascularized Interpositional Periosteal-Connective Tissue (VIP-CT) flap for aesthetic anterior soft tissue, and the importance of provisional restoration and impression taking stage with customized impression coping.

With the development of treatment of hard and soft tissue around the implants, the implant restoration is increasingly used in the maxillary anterior region which is very important aesthetically. However, the aesthetic reconstruction of the maxillary anterior region is still challenged. Three following conditions should be fully satisfied for aesthetic prosthesis restoration; reconstruction of hard tissue, soft tissue and harmonic prosthesis. In this case report, hard and soft tissue augmentations were performed at atrophied maxillary incisor. Additionally, customized impression coping and provisional restoration were used to make the final restoration.

Periodontal tissue destroyed by inflammation is difficult to achieve regeneration of the tissue and esthetic restorations only by surgical methods. In particular, improvement of esthetics is more difficult if the problem is related to the implant. A 23 year old woman suffered from unesthetic anterior implant prosthesis. According to her dental history, a repeated bone graft and soft tissue graft failed at a local dental clinic. It was needed to resolve the inflammation and to improve the esthetics. A free gingival graft and ridge augmentation accompanied by guided bone regeneration and a vascularized interpositional periosteal connective tissue graft was performed. Instead of implant prosthesis, a conventional fixed bridge was adopted for better esthetic result. The patient was satisfied with the esthetic conventional fixed prosthesis. This case report introduces esthetic rehabilitation of unesthetic implant prosthetics in the maxillary anterior dentition by a combination of surgical and prosthetic approaches.

As the increased certainty of osseointegration, new parameters are now being used to assess implant success. Accordingly, patients' and clinicians' high demands and expectation for esthetics have expanded and implant-supported restorations show better esthetic outcomes. The pre-implant treatment planning process, the implant surgical steps and the post-surgery prosthetic process can affect all esthetic outcomes. Prevention of esthetic implant failures can be achieved by appropriate treatment at each stage, considering the 3 factors of alveolar bone, soft tissue, and implants. It is necessary to achieve the esthetic implant prostheses followings: minimal invasive surgery, bone augmentation, ideal 3-dimensional implant position, peri-implant soft tissue management, and provisional restorations to optimize peri-implant soft tissue architecture.

Soft tissue collapse around prepared teeth and pontic is inevitable after removal of the provisional restoration during the impression taking procedures. When inserting gingival retraction cord, soft tissue is displaced to an undesired contour. Viscosity of impression material also causes gingival displacement. Therefore, the consideration to transfer the prosthetically contoured soft tissue to master cast is required, especially in the esthetic area. In this report, the methods to maintain the soft tissue contour and transfer to the mastercast will be introduced. Harmonious contour of the soft tissue can be achieved with provisional restoration and be transferred to the master cast with two different techniques mentioned in this case report.

Aesthetic impression is emphasized in the recent field of implant restoration. However, there is limitation of creating proper shape of soft tissue as well as cervical emergence profile due to the use of pre-existing healing abutment in the process of initial post-operative soft tissue healing period. Designing the shape of abutment into the final customized abutment instead of its original shape helped to achieve more aesthetic implant restoration by applying healing abutment which could minimize the malposition and recession of soft tissue. In this study, soft tissue healing was promoted using the post-operative customized healing abutment and thereby obtained the result of more aesthetic and functional restoration by minimizing displacement of soft tissue in the process of applying final customized abutment.
